Stocks fall for a fourth day

Stocks fell Tuesday on mixed economic reports and concern about a government shutdown. Stocks edged lower in early trading, before reversing the losses to move modestly higher by late morning. The gains then fizzled out.

Investors struggled with conflicting news about the economy on Tuesday. One report showed that home prices in July rose the most in more than seven years. Another showed that Americans' confidence in the economy slipped in September.

Investors are searching for direction after the Federal Reserve's surprise decision last Wednesday to keep its stimulus program intact. They had expected a reduction in the Fed's $85 billion in monthly bond purchases. Investors are now parsing economic reports and comments from Fed officials to gauge the central bank's next move.

Some are also nervous about political gridlock in Washington. They were concerned that the federal government could shut down because Washington lawmakers appear to be making little progress in budget talks.

"A government shutdown starting next week is looking increasingly likely," said Jim Russell, a regional investment director at U.S. Bank. "That will not be welcomed by the capital markets."

But Brad Sorensen, director of market and sector research at Charles Schwab, thought that worries about a government shutdown would ultimately be short-lived.

"Investors are becoming a little bit immune to the games that Washington has started to play," Sorensen said. "Investors with a stronger stomach should probably buy the dip."

Stocks, for example, plummeted in the summer of 2011 as lawmakers wrangled about raising the debt ceiling. The market also sagged in October last year before the Presidential elections, on concerns that a divided government would be unable to agree on tax reform. Each time though, backed by the Fed's economic stimulus, the market came back stronger.

After falling 2 percent in October of last year, the Standard & Poor's 500 index rose for seven straight months, gaining 15 percent.

On Tuesday, the Dow closed down 66 points, 0.4 percent, to 15,334. The S&P 500 index fell four points, or 0.3 percent, to 1,697. The Nasdaq composite, however, edged up three points, or 0.1 percent, to 3,768.

Stocks edged lower in early trading, before reversing the losses to move modestly higher by late morning. The gains then fizzled out.

Phone company stocks were the biggest decliners among the 10 industry groups that form the S&P 500. Industrial stocks were the biggest gainers.

Before the market opened, a survey showed that home prices rose the most since February 2006. A revival in housing has been one of the bright spots for the economy.

In another key economic gauge, the Conference Board, a New York-based private research group, said that its consumer confidence index dropped to 79.7 in September, down from August's 81.8.

Consumers' confidence is closely watched because their spending accounts for 70 percent of U.S. economic activity. Confidence has grown since the Great Recession, but it hasn't hit a reading of 90, which typically accompanies a healthy economy.

They S&P 500 index is just 28 points below its all-time high reached last Wednesday, when investors were initially thrilled that the Fed extended its economic stimulus. Since then, the market has fallen each day as doubts emerge about the outlook for the economy, and budget negotiations.

In government bond trading, the yield on the 10-year Treasury note rose fell as investors bought bonds. The yield dropped from 2.70 percent late Monday to 2.66 percent, its lowest level in six weeks. The yield on the note is a benchmark for rates of consumer loans.
